About Us

Our Progress is Your Profit

Everything we do at Coronga is driven by our desire to see our clients maximise their prime lamb profit.   Whether you are joining merinos or meat breeds, maidens or matrons, feed-lotting or far west, we have White Suffolk Rams that can do the job you need. Strict selection criteria for our rams aim to meet your breeding needs.


Figures for the Future

At Coronga, our figures give buyers confidence that our white suffolk rams will perform.  ASBVs are a reliable way to focus your prime lamb breeding program on what is important. In combination with the data, we diligently select structurally sound rams with a strong emphasis on conformation and feet.

Understanding Lambplan ASBV

Experienced Breeders

James and Kirrily welcomed the opportunity to take the helm of Coronga White Suffolks in 2021. Together with their parents, Peter and Julie Jackson, they have been breeding quality, profit-maximising rams for prime lamb production for over 25 years at Coronga. Lambplan, artificial breeding and commitment to record keeping and flock health have produced consistent progress toward our breeding goals. We've done the work so you can reap the rewards. 

Coronga Breeding Goals

Our Rams are Balanced

Our Rams are Balanced

Our Rams are Balanced

We strive for the best balance between growth, muscle, eating quality and an efficient birth weight. Selection of the best rams for you will depend on the ewes you use. Coronga rams are used over Merino, Dohne, Corriedale, first cross and maternal composites, with great success over maiden and mature ewes. The very best ram for each of you may vary, but we pride ourselves on providing a balanced offering.

Muscling & Fat/Lean

Our Rams are Balanced

Our Rams are Balanced

Coronga rams continue to excel for muscling. The resultant high dressing percentages and yield of prime cuts adds more dollars to the value of lambs, and their sires. We are trending to less leanness, with many of the rams have pFat close to 0 or positive which assists the early finish of lambs and gives flexibility to producers in what age to sell their lambs.  

TCP and LEQ

Our Rams are Balanced

Fecundity & 1st cross ewes

 The Terminal Carcase Production (TCP) index is still a useful tool for ram buyers. The identification of eating quality genes is reflected in the Lamb Eating Quality (LEQ) index. This enables progress to be made by breeders and passed on in the Coronga “balanced package” to commercial prime lamb producers.

TCP Index factsheet

Fecundity & 1st cross ewes

Flock Health - worm control

Fecundity & 1st cross ewes

The fecundity of our flock is demonstrated in the catalogue by the number of multiples in the sale rams. They should make excellent terminal sires, and their fecundity will enhance their value as sires to breed cross bred ewes. 

There is solid support for retaining Coronga White Suffolk x Merino ewes.  High lambing rates and milk, plus carcase attributes, can result in top quality breeding ewes. 

Flock Health - worm control

Flock Health - worm control

Successful worm control at Coronga is due to pasture management with cattle grazing rotations, and strategic drenching and drench rotation. As Coronga worm counts as always been very very low we have not previously submitted counts for evaluation of WEC ASBV. All our Lambplan indexes including WEC values could probably be higher by about 2%  if we submitted WEC. These indexes include LEQ and TCP.  

Flock Health - vaccination

Flock Health is a major focus at Coronga:

  • 19 year history of Gudair vaccination
  • All rams are Brucellosis-free accredited
  • Comprehensive vaccination program
  • Every ram is closely inspected for overall health, soundness and absence of testicular abnormalities.
